Rospars; INRA: examinateur English summary English summary Taste is one of the fundamental senses by which animals can detect food sources (sugars, salts, lipids, amino acids) but also noxious compounds dissolved in aqueous solution or adsorbed on surfaces (leaf, cuticle). Unlike olfaction, where only cephalic organs are involved in the detection of volatile compounds, in insects, gustatory sensilla are located on different parts of the insect body (mouthparts, legs, wings, ovipositor) which results in the precise spatial location of the stimuli which excite them. These sensilla are involved in different behaviours and might therefore be tuned to different types of contact chemosensory stimuli. These functional constraints imply a different organisation of the nervous centres processing the information received from gustatory receptor neurons. Whereas projections from olfactory receptor neurons are clearly chemotopic, comparatively little is known on how gustatory neurons project to the central nervous system and how signals are encoded and processed by central neurons. In different insect species, including Lepidoptera, responses of gustatory receptor neurons situated on the tarsae and the abdomen have been described. However, physiological characteristics of antennal gustatory sensilla and the behavioural context in which they are used are only starting to be investigated. The objectives of this thesis were to study the gustatory neurons of contact chemosensory sensilla present on the antennae of adult Spodoptera littoralis using two different approaches: an electrophysiological approach of testing soluble chemicals and recording the firing pattern of these neurons; and a neuroanatomical approach of staining their pathways and target regions in the brain. Our electrophysiological observations show that taste sensilla possess neurons that respond to sugars like sucrose, fructose and glucose and to NaCl. We could not identify a gustatory receptor neuron responding to bitter compounds or amino acids, but the range of tested substances was limited and nothing is known on the behavioural significance of such compounds. We were able to test the sensitivity along the antenna of the sensilla located on the lateral side of the antenna but no differences were noticed. However, sensilla in males and females differed in sensitivity. In females, the intensity of responses was found to be weaker for the sensilla on the dorsal side of the antennae than for those on the ventral side. Antennation is a behaviour frequently described before mating or egg laying. The precise role of contact chemoreceptors in this kind of behaviours is however, unknown. For a conclusive interpretation of our data on the neuronal coding and central representation of taste English summary information from the antennae, the involvement of antennal gustatory receptors in mating behaviour, host-plant detection and oviposition and their possible interactions with olfactory receptor neurons remains to be investigated. A scanning electron microscopic study showed no sexual dimorphism in the distribution of taste sensilla on the antennae. Mass fills of antennal afferents and backfills of individual contact chemoreceptive sensilla using Neurobiotin revealed 4 distinct projection areas of antennal gustatory sensilla. Two areas are within the deutocerebrum: the antennal motor and mechanosensory centre (AMMC) and a region situated posteriorly to the antennal lobes. The two other areas are in the tritocerebrum/suboesophageal ganglion complex. As our electrophysiological investigations showed that different neurons in the same sensillum respond to different stimuli, including mechanical stimuli for one of the neurons, it can be hypothesized that the projection areas are functionally distinct. No evidence for somatotopy of sensillar afferents originating from different parts of the antenna was found, with the methods used. A more detailed analysis of branching patterns within each target zone might reveal some form of somatotopy, however. 3 Résumé en français Résumé en français La gustation est un sens essentiel à tous les animaux, leur permettant de détecter aussi bien des substances à valeur alimentaire (sucres, sels, lipides, acides aminés) que des substances potentiellement toxiques dissoutes en solution aqueuse ou adsorbées sur des surfaces (feuille, cuticule). Contrairement à l’olfaction qui détecte des substances volatiles diffusées dans l’air ambiant, la gustation est étroitement liée à une localisation spatiale des stimuli, impliquant un positionnement très précis de l’organe sensitif. Ces contraintes fonctionnelles impliquent une structuration complètement différente des centres nerveux traitant les informations issues de ces récepteurs chimiques. Dans le cas de l’olfaction, les projections des récepteurs olfactifs sont clairement chimiotopiques, les afférences olfactives se regroupant sur des zones de convergence en fonction des récepteurs membranaires exprimés dans les neurones olfactifs. Dans le cas de la gustation, les projections des récepteurs gustatifs seraient étroitement associées aux projections des mécanorécepteurs, selon une organisation somatotopique. Par rapport au système olfactif, les connaissances sur le fonctionnement du système nerveux gustatif chez les insectes sont restées en retrait, essentiellement à cause des difficultés inhérentes à la caractérisation des projections et à la difficulté de déterminer si à la somatotopie se superpose une chimiotopie. Nous avons étudie le système gustatif associé aux antennes de lépidoptères, en prenant pour modèle la noctuelle du coton Spodoptera littoralis. Les récepteurs gustatifs des antennes sont impliqués dans différents comportements, comme l’ont montré notamment des protocoles d’apprentissage associatif. Cet organe est remarquable chez les lépidoptères car il est dépourvu de muscles (à l’exception de la base) et caractérisé par la duplication de segments homologues (les segments antennaires) portant une distribution d’organes olfactifs et gustatifs identique de segment à segment, avec néanmoins des différences progressives en allant de la base vers l’extrémité. Nous avons abordé d’abord l’aspect fonctionnel des neurones en caractérisant par des techniques électrophysiologiques le spectre de réponse de ces neurones gustatifs à l’aide de stimuli simples (sucres, sels, acides aminés, composés amers). Dans une deuxième phase du travail, la structuration du système antennaire a été abordée par des marquages cellulaires à la neurobiotine de sensilles gustatives individuelles. Ce travail a été précédé par une cartographie précise de la localisation des sensilles gustatives à la Résumé en français surface de l’antenne, par microscopie électronique à balayage. La caractérisation des projections a nécessité l’utilisation d’outils de reconstruction 3D de manière à pouvoir estimer la constance des projections issues de récepteurs homologues entre différents insectes et à estimer la distribution spatiale des projections issues de neurones différents chez le même insecte. L’antenne de l’espèce S. littoralis est constituée de 3 parties : le scape, le pédicelle et le flagelle. Seul le flagelle, qui est constitué d’environ 70 segments, porte des sensilles gustatives. Chaque segment a une partie ventrale et une partie dorsale. Au niveau de la partie ventrale on trouve 4 sensilles gustatives: 2 latérales et 2 médiales. Les premiers segments situés à la base de l’antenne sont dépourvus de sensilles médiales. On commence à les observer à partir des 6ème-7ème segments à la base de l’antenne. Au niveau du dernier segment situé à l’extrémité, on observe une couronne de sensilles gustatives (6 ou 7). La partie dorsale de l’antenne est couverte d’écailles, mais on peut observer 2 sensilles gustatives médiales au niveau de chaque segment

    Elytra Reduction May Affect the Evolution of Beetle Hind Wings

    Zoomorphology https://doi.org/10.1007/s00435-017-0388-1 ORIGINAL PAPER Elytra reduction may affect the evolution of beetle hind wings Jakub Goczał1 · Robert Rossa1 · Adam Tofilski2 Received: 21 July 2017 / Revised: 31 October 2017 / Accepted: 14 November 2017 © The Author(s) 2017. This article is an open access publication Abstract Beetles are one of the largest and most diverse groups of animals in the world. Conversion of forewings into hardened shields is perceived as a key adaptation that has greatly supported the evolutionary success of this taxa. Beetle elytra play an essential role: they minimize the influence of unfavorable external factors and protect insects against predators. Therefore, it is particularly interesting why some beetles have reduced their shields. This rare phenomenon is called brachelytry and its evolution and implications remain largely unexplored. In this paper, we focused on rare group of brachelytrous beetles with exposed hind wings. We have investigated whether the elytra loss in different beetle taxa is accompanied with the hind wing shape modification, and whether these changes are similar among unrelated beetle taxa. We found that hind wings shape differ markedly between related brachelytrous and macroelytrous beetles. Moreover, we revealed that modifications of hind wings have followed similar patterns and resulted in homoplasy in this trait among some unrelated groups of wing-exposed brachelytrous beetles. Our results suggest that elytra reduction may affect the evolution of beetle hind wings.

They have serious impacts, whether agronomic, veterinary or medical. The present review discussed several aspects in the behavioral ecology of Meloidae. The sexual behavior phases varied among meloid species including searching for mate, approaching and some physical contacts ending in mating. Cantharidin usually be employed as a nuptial gift in the courtship. Courtship may be repeated and the assortative mating may be taken place. Mate-guarding was, also, recorded for certain species. The present work comprehensively reviewed, also, the feeding tactics, defensive measures and cleaning antennae among the non-sexual behavioral patterns of Meloidae. An intensive attention was paid to the phoresy behavior focusing on triungulin structural adaptation for phoresy, scenarios of phoresy and phoresy as dispersal way as well as a taxonomic tool. The uses of sexual and egg-laying behavior in the systematics of Meloidae had been presented. Key words: Courtship, nuptial gift, cantharidin, oviposition, phoresy, defensive behaviour, cleaning behaviour, physiology.

    — THE BLISTER BEETLE TEICRANIA SANGUINIPENNIS— BIOLOGY, DESCRIPTIONS OF DIFFERENT STAGES, AND SYSTEMATIC RELATIONSHIP. By J. B. Parker, Of the Catholic University of America, Brookland, District of Columbia, and Adam G. Boving, Of the Bureau of Entomology, United ^States Department of Agriculture. INTRODUCTION. The family Meloidae is distributed all over the world and has been the subject of the studies of several prominent entomologists. Nevertheless, it is a group but insufficiently looked into from the different angles of natural history and especially has the biology of the family and the description of its different larval stages been less worked out than is generally realized. The metamorphosis was unknown until 1851 and since then only a few important contributions have appeared on this subject, namely, the classical papers of Newport, Fabre, Mayet, Riley, Beauregard, Kunckel d'Herculais, and the modern, numerous, very important pub- lications by A, Cros, who has given complete or partial accounts of the biology of many of the hitherto little known or entirely unknown genera and species. However, as mentioned, much knowledge is still lacking of the life history and structural details of several important forms, this being especially true of our American species. Concerning these little has been written since Riley's famous publications on Epicauta and -Hornia. Thus, the life history of a genus so common as Macro- hasis has not yet been fully investigated, though F. B. Milliken has recently contributed some valuable information. Of 31 North American genera we have complete biological records of only 1, namely Epicauta; and partial records of 2, Hornia and Macrohasis; the life history of the remaining 29 being unknown or known only through European publications on European species.

    International Journal of Research in BioSciences Vol. 2 Issue 3, pp. (1-45), Julyl 2013 Available online at http://www.ijrbs.in ISSN 2319-2844 Review Paper Global zoogeography and systematic approaches of the blister beetles (Coleoptera: Meloidae): a bibliographic review Karem S. Ghoneim Faculty of Science, Al-Azhar University, Cairo, EGYPT (Received 5 April, 2013, Accepted 22 June, 2013) Abstract Blister beetles, or oil beetles, belong to the family Meloidae in order Coleoptera. They are cosmopolitan and distributed allover world except for New Zealand, Antarctica and some regions of Oceania. Some blister beetles are agricultural pests but all produce cantharidin which dangerously affect both animals, other than many canthariphilous insects, and man albeit it is used, in some parts of the world, to treat certain ailment cases such as cancer. The present work reviews the worldwide distribution of Meloidae throughout temperate, arid, sub-tropical and tropical regions, focusing on the most important identified subfamilies, tribes, genera and species in each region. Also, this review comprehensively highlights the systematic efforts in several parts of the world including various taxonomic methods and tools, especially the adult morphology, triungulin morphology, sexual and egg-laying behavioural patterns, adult anatomy and molecular data which have been recently used to disclose some elusory systematic problems. Keywords: Meloinae, Eleticinae, Tetraonycinae, Lyttinae, Nemognathinae, phylogeny, morphology, anatomy, triungulins. Introduction The patterns of the past, present, and future distribution of animals in nature and the processes that regulate these distributions are concerns of zoogeography [1,2]. Also, it provides the basis for environmental protection and resource management [3]. Careful and accurate identification and classification of living organisms are of vital importance ]4[.

Ghoneim Faculty of Science, Al-Azhar University, Cairo, Egypt. E-mail: [email protected]. Accepted 22 January, 2013 Blister (oil) beetles, family Meloidae, are distributed throughout the world except for New Zealand, Antarctica and most Polynesian islands. They are characterized by their complex biology including hypermetamorphosis and diapause. The present review discusses the embryonic development of several meloid species belonging to various genera. Concerning the postembryonic development, this work reviews the life histories of some meloid species focusing on the adult longevity, preoviposition period and oviposition period. It reviews, also, the adult reproductive potential of several species and pays some attention for the immature stages, particularly the larvae of bee - and grasshopper- associated beetle species. Trials had been achieved for maintaining laboratory colonies of some meloids in different parts of the world for which failure was reported more than success. In addition, the present work shed some light on the diapause in Meloidae as an escape in time from the unfavorable environmental conditions. Key words: Blister beetles, embyogenesis, hypermetamorphosis, triungulin, longevity, oviposition, fecundity, fertility, diapause. INTRODUCTION The family Meloidae (order Coleoptera) is commonly holding the host (Gillott, 1995; Di Giulio and Bologna, known as oil or blister beetles. Meloid species are 2007). widespread throughout the world except for New Zealand Adult beetles can be recognized by morphological and Antarctic (Arnett et al., 2002).
